The reassignment comes with a choice for Schafer, who's return to camp this spring served as a second chance to reinvent himself as a two-way player. The left-handed-throwing former outfielder tried to carve out a hybrid role as a reliever/outfielder/pinch-runner. But after struggling in both of his two appearances on the mound, the club will now let Schafer decide whether he wants proceed as a pitcher or a position player.

Poncedeleon's emotional return to the mound on Feb. 25 completed a nearly 10-month recovery from a fractured skull suffered when he was hit with a comebacker last May. The righty allowed five earned runs in three appearances this spring.

Schrock, one of two players acquired this winter in the deal that sent Stephen Piscotty to Oakland, was the only player reassigned who hadn't appeared in a Grapefruit League game this spring. He continues to rehab an oblique injury suffered on Feb. 19.
